PORTABLEMACHINE CAPABLE OF BENDING 0R MOLDING SHEET-ZINC.

SPECIFICATION forming part of Letters Patent No. 753,844, dated March 8, 1904'.

Application filed March 31, 1902.

To all whom it may concern:

Be it knownthat I, Aueus'rn HUBERT BIF, a citizen of the French Republic, and a resident of Boisguillaume, near Rouen, France, have invented a new and useful Portable Machine Capable of Bending or Molding Sheet-Zinc and Sheet-Iron and of Making Tubing, of which the following is a specification.

In the drawings, Figure 1 is a partial perspective view of the machine. Fig. 2 is an elevation. Fig. 3 is in part a plan of the complete apparatus and in part a plan of the table and its accessories. Fig. 4 is a section from A to B in Fig. 2. Fig. 5 is a section from C to D in Fig. 2. Figs. 6, 7, 8, and 9 are sectional views showing the method of working the machine to make a round molding or torus or spouting. I

A table 1 is provided supported on trestles 2. At each end of the table there is secured a shoe 3, pierced by an opening in which is rotatably mounted a spindle 5, the latter at its extremities being provided with counterpoises 17. This spindle 5 supports a rail 15, which extends between the said shoes and is supported at a point adjacent one of the horizontal edges of the table, as can be more clearly seen from Figs. 6 and 9 of the drawings. For the purposes of imparting motion to the rail I provide an operating-lever 16, which may be conveniently secured by its ends, as seen in Fig. 2. The motion of this rail is limited to a rotary one, the axis of rotation coinciding with said horizontal edge of the table, the base of the rail when in its normal position extending in the same horizontal plane as the surface of the table, as can be seen in Figs. 6 and 8. At the extremities of the table and beyond the shoes are secured irons or sup. ports 6, which receive the ends of supporting-arms 7 the latter being inclined upwardly and supporting between their upper-ends the interiorly-threaded socket 8, provided with feet 9, which permit of its securement to the said arms. A threaded shaft 10 passes through the socket and carries at its upper end a handwheel 14 for the purpose of rotating the shaft Serial No. 100,724. @No model.)

adjacent and in parallel alinement with the guide-grooves 18 thereof, thus preventing The horizontal flange of any motion of the iron13 save a purely ver- I tical one.

In operation the sheet-iron or other metal is placed on the table 1, the one side thereof being fastenedto the table by bringing the iron 13 down to engage the upper face of the metal, at which time the rail 15 is rotated by means of the lever 16 and the bend formed to according to whatever angle is desired, the rotation of the rail being limited to this desired angle. If it is desired to makea round molding, amandrel 21 is employed consisting of two half-circular irons connected together, but slightly separated to allow the edge of the sheet metal to be introduced therebetween. An aperture is made toward the end of the mandrel, and by the insertion of tongs or the like the material may be removed after the molding has been formed. After the material has been inserted in themanclrel, as stated, the. iron 13 is brought down to secure the mandrel between the table and its under face, as seen in Fig. 6, an angle 23 in this instance being' employed secured to the under faceof the iron 13, which limits any rearward movement the mandrel might have a tendency to make, as illustrated in Figs. 7 and 9 of the'drawings. Pins 24, such as illustrated in Fig. 2 of the drawings, may be employed to secure the angle-iron to the iron 13, thus permittingsaid angle-iron to be readily removed.

Having now fully described my invention, what I claim as new, and desire. to secure by Letters Patent, is-

The combination with the table of shoes secured adjacent the ends thereof, a spindle journaled in the shoes with a rail supported by the spindle, a lever for operating the rail, a

an angle-iron detachably secured to the under face of said first-named iron, said rail having its base normally lying in horizontal alinement with the surface of the table.

In testimony whereof I have hereunto set my hand in presence of two Witnesses.
